UNITED STATES PATENT OFFICE.

GRANVILLE NICHOLSON, OF NEW YORK, N. Y.

WlRE-STRETCHER.

SPECIFICATION forming part of Letters Patent No. 229,449, dated June 29,1880.

Application filed March 1, 1880. (Model.)

To all whom tt may concern:

Be it known that I, GRANVILLE NIoHoL- SON, of the city of New York, inthe county and State of New York, have invented a certain new andImproved Tool for Fencing and other purposes, of which the following isa specification.

. In the construction of wire fences it is necessary to employ a toolfor stretching the wire tightly, so as to take up all the sag and createa tension upon the wire before fastening it to a post.

It is also desirable to employ a crowbar for use in setting posts andother purposes incident to putting up a line of wire fence.

My improved tool consists in a bar having acrowbar-point and providedwith a shoulder and a pivoted cam-dog for griping the wire and holdingit between said camdog and shoulder, and so constructed that it may beswung inward toward the axial line of the bar from either side thereof,whereby greater facility in the use of the tool is secured than it thedog were capable of swinging only upon one side of the bar.

In the accompanying drawings, Figure 1 represents a portion of a fenceand a perspective view of my improved tool, showing the manner of usingit in straightening the fence-wires and Fig. 2 represents apartlysectional side view of said tool.

Similar letters of reference designate corresponding parts in both thefigures.

A designates a bar of steel or iron, having at a little distance fromone end a shoulder, a, and having a cam-dog, B, pivoted to one side bymeans of a rivet, b. The cam-dog B is represented as having a serratedor roughened face, 0, which may not, however, be essential, and it ispivoted in such relation to the shoulder a that when turned so as tostand in line with the bar the space between the shoulder a and the face0 of the dog will be somewhat less than the thickness of the strands ofwire composing the fencing, as clearly shown in Fig. 2.

It will be observed that the cam-dog B is so constructed and arrangedthat it may swing inward toward the axial line of the bar from eitherside thereof, and that therefore the bar may be used with much greaterconvenience than if the dog could be swung upon one side only, for thereason that itmakes no difference in using the bar which of the twoopposite sides is uppermost, while in the latter case the user must usecare to have a particular side of the bar uppermost.

The calndog is here represented as arranged in a recess, d, in the sideof the bar A, and the shoulder a as formed by a lug or projection formedupon the side of the bar; but if desirable the recess d might bedispensed with, the side of the bar being slightly fiatened to form aseat for the dog, or the recess might be made deeper, so that one endthereof would form the shoulder, and in such case the lug or projectionon the side of the bar would be dispensed with.

The end of the bar A has formed upon it a crowbar-point, A, and hence itanswers all the purposes of an ordinary crowbar, and enables a separatecrowbar to be dispensed with.

In using my improved tool the fence strand or wire 0 is caught and heldbetween the ser rated face 0 of the cam-dog B and the shoulder a and thepoint A rested against the post O as a fulcrum.

By moving the bar down in the direction of the arrow f the strand orwire e is stretched sufficientl y to keep it from sagging, and is thenfastened to the post by staples g or otherwise.

What I claim as my invention, and desire to secure by Letters Patent, is

The bar A, having a crowbar-point, A, and the shoulder a, and providedwith the camdog B, constructed and arranged so that it may be swung fromeither side of the bar inward toward the axial line of the bar,substantially as and for the purpose herein described.
